Abstract :
The aim of this study was to compare the immediate implant mobility and the pull-out resistance of large diameter dental implant (4.5 mm) with a standard size (3.25 mm) implant. Two groups consisting of 18 implants, were placed in 5 embalmed human mandibles. The result of Periotest showed the same initial stability for the two groups. The maximum pull-out force for large diameter implants was 16% greater than that for the small diameter implants, although this difference was not statistically significant. There were significant positive correlation (p<0.05, p<0.01) between the pull-out force and the bone density for the large and small diameter implants
